The CM – 100 Air Permeability of Portland Cement by Fineness Device is used in measuring the fineness of Portland cement in accordance with ASTM and AASHTO standards. He fineness is measured in terms of the specific area of cement expressed as total surface area in square centimeters per gram. In operation, the apparatus draws a definite volume of air through a prepared bed of cement. The porosity of the cement, which is function of the size of the cement particles determines the rate of air flow through the bed
